TRANSCRIPT

  • I have a significant role to play in maintaining ecosystem functionality and biodiversity.

    I AM FIRE

    I occur natural through lightening to perform my

    duties. Humans have altered most of the

    natural ecosystems and if these ecosystems are mismanaged, I consume

    everything in my path and leave a catastrophic

    signature.

    Im also anthropogenic

    occurring. Humans use me as a land

    management tool

    I m your best friend And also, I can be your worse enemy

  • SOUTH AFRICA

    Divided into nine provinces. Has a wide range of climatic conditions and

    vegetation types. Its diverse in terms of environmental distribution. High levels of biodiversity. Its unique social structure has resulted in:

    Diversity of languages, Literacy levels, Geographical spread and, Population communication abilities.

  • FIRE MANAGEMENT

    Fire contributes to Earth System Science (ESS).

    Fire as a driving factor for ecosystem and biodiversity.

    Fire management (Forester);

    Prevention,

    Protection, and

    Suppression.

    Fire as land management tool.

  • FIRE MANAGEMENT cont.

    Fire ecology;

    Fire dependent ecosystems,

    Fire independent ecosystems,

    Fire sensitive ecosystems, and

    Fire influenced ecosystems.

    Integrated fire management.

    Old The Hedgehog Concept.

    New The Fox Concept.

  • Fire independent ecosystems

    Fire dependent ecosystems

    Fire sensitive ecosystems

    Fire influenced ecosystems

    (Adapted from S.A. Biomes) Low et al., 1998

    TYPES OF FIRE ECOSYSTEMS

  • CONCLUSION

    South African environmental conditions are complex, not complicated.

    Understand the conditions for better management.

    Link + Interaction = Functionality

    Fires can be beneficial.

    E.g. management of the ecosystems.

    Fires can also have detrimental effect.

    E.g. Destruction of the land.
